<p>An electrostatic air cleaner comprises a corona charging section and a precipitation section. The charging section comprises a first and a second array of substantially parallel earth wires, each array being disposed in a respective plane substantially perpendicular to the direction of air flow, and a third array of substantially parallel corona wires sandwiched between the first and second arrays. With this design, the spacing between earth wires and the spacing between corona wires can be selected independently to obtain the most favourable corona discharge conditions. The arrangement also enables easy cleaning of the earth wires.</p> |
